The Study On The Power Supply Reliability Of 10kV Power Distribution Grid For Minhou Area

In recent years, with the vigorous development of China’s electric power system, China’s power industry technology into the stage of rapid development, as some rise UHV pressure technology, long-distance transport a wide range of energy, power grids and unit capacity expansion, AC and DC hybrid technology, the popularity of smart grid technologies, electric power systems have become more complex, safe and reliable operation of the grid to highlight the growing problem, then the electric power system reliability to ensure power grid management will naturally become an important subject safe and reliable operation. To achieve the sustainable development of the power grid and strategic objectives, to ensure network equipment health, improve enterprise management level electricity, supply reliability needed to manage such scientific management methods to manage and measure the development trend of the entire grid, and its derived electricity system reliability of the indicators is as a reflection of the health and electricity grid equipment enterprise management level. as well as society’s growing demand for electricity based on indicators, and in network planning, product design and installation, equipment repair and maintenance and other aspects guiding role can not be ignored. The power system, especially 10KV Power supply reliability study is the distribution network planning and design, equipment design and installation and commissioning, production infrastructure construction, service and other aspects of the user -powered production quality and management level of expression. Thus in-depth study reliability management, improve power supply reliability level of business management, is of great significance for the entire grid.This paper describes the first distribution network reliability research background, significance and research status, then according to the structural characteristics of 10KV distribution network and operational characteristics, describes the basic distribution network reliability concepts and basics. Then describes distribution network reliability evaluation index system, power distribution grid reliability index lists how the statistics, calculation, analysis and evaluation, and through the calculation of the index system in recent years, regional distribution network reliability MINHOU the indicators, the use of the statistical analysis of the results, the actual introduction of the guiding role of power distribution system. Then MINHOU region in recent years from the pre-arranged cause analysis and fault outage responsibilities start affecting distribution network reliability study of the main factors, and the use of gray correlation analysis method to the extent of the main factors affecting the intuitive sort, Sort conclusions drawn grid structure and distribution network wiring, the failure rate of the device itself, planned outage schedule and natural environmental factors, and put forward to improve distribution grid reliability and effective measures. Finally, the proposed construction MinHou Sugarcane Area High reliability demonstration area to study and make major approach.In this paper, regional distribution network reliability MINHOU conducted in-depth research, the use of recent years, the reliability of the data, and use the scientific method to analyze the distribution network trends and innovative construction and international raised a considerable level of high reliability demonstration area, which are for the future development of the distribution network MINHOU region has great significance.
